【 摘 要 】

This paper presents a complementary current-mode 2nd order Gm-C filter for 5G and other broadband applications. The filter structure is based on 2 complementary differential pairs in order to achieve both low noise and high frequency performances. A bandwidth of higher than 1GHz is achieved with a gain of 0dB and an in-band IIP3 of 29dBm, consuming less than 27mW from a 1.8V supply. The filter is fabricated in a 65nm CMOS process with a core circuit area of 0.1mm × 0.08mm.
